Question: When using . (DotProduct in VectorCalculus) I get Error, (in property/ConvertProperty) invalid input: PropRange uses a 2nd argument, b, which is missing

Pretty much the title.

At first I thought something's wrong with my vectors, but even something like <1,1,1>.<2,2,2> produces this error.

I have restart in the very beginning of my worksheet and with(VectorCalculus): right after.

I'm using the 64 bit version of Maple 18 on Windows 10, if this matters.

Please Wait...
